Collective-dissipation-induced dark and metastable-like states for enhanced quantum battery performance
Achraf Khoudiri, Asghar Ullah, Abderrahim El Allati +1
We investigate the role of symmetry-protected dark states and metastable-like frozen states in the autonomous charging dynamics of open quantum batteries described by a transverse-…
Multimode phonon-mediated enhancement of entanglement and competing synchronization in cavity magnomechanics
Z. Imara, Jia-Xin Peng, E. K. Berinyuy +2
The generation of quantum correlations in hybrid quantum systems remains a central challenge due to the intrinsic limitations of linear interactions. In cavity magnomechanical plat…
Correlation Enhanced Autonomous Quantum Battery Charging via Structured Reservoirs
Achraf Khoudiri, Abderrahim El Allati, Youssef Khlifi +3
In this work, we investigate autonomous charging of a quantum battery coupled to a structured reservoir composed of two qubits, each locally coupled to its own bosonic thermal bath…
Phase-switchable nonreciprocal entanglement via magnon squeezing in ring-cavity optomagnomechanics
Z. Imara, A. El Allati, A. Belfakir +2
Cavity optomagnomechanics provides a versatile platform to explore macroscopic quantum correlations, particularly nonreciprocal entanglement. In this work, we propose a theoretical…
From spectral structure to sensing limits in quantum thermometry
Youssef Aiache, Simone Cavazzoni, Abderrahim El Allati +2
The precision of a quantum thermometer is fundamentally constrained by the spectral structure of the probe itself, and a systematic mapping between the configurations of energy lev…
Suppressing Self-Discharging of Quantum Batteries by Cavity Interactions
Anass Jad, Abderrahim El Allati, Mohammad B. Arjmandi
We analyse a two-cavity architecture, in which a lossy cavity hosting qubits is coherently coupled to an auxiliary cavity, as a resource for the storage phase of an open quantu…
